Yield:96-50-4 95%

Reaction Conditions:

with iodine in dimethyl sulfoxide at 80; for 1 h;Green chemistry;

Steps:

Procedure for preparation of 2-aminothiazoleby starch NPs

General procedure: A mixture of methylcarbonyl (0.5 mmol), thiourea(0.5 mmol), iodine (0.5 mmol), DMSO (2 mL) and 10 mgStarch NPs were stirred at 80 C. After completion of thereaction (monitored by TLC, petroleum:ethyl acetate, 4:1),the reaction was quenched by the addition of 10 mL distilledwater. The aqueous solution was extracted withEtOAc (3 9 10 mL) and the combined extract was driedwith anhydrous Na2SO4. The solvent was vacuumed, andfinally, the resulting precipitate was recrystallized byEtOH.
